not running, check for opens, shorts or grounds.

 

 

WITH POWER OFF: Turn motor to check for locked

 

 

rotor. Replace burner blower motor as needed.

 

Burner transformer

Check for 120VAC supplied to primary of burner

 

 

transformer. If no voltage is present, trace wiring back

 

 

to centrifugal switch of main fan motor. If voltage is

 

 

present, check for 24VAC supply at transformer

 

 

secondary. If there is primary voltage but no secondary

 

 

voltage, replace burner transformer.

 

Centrifugal switch of burner

Check for 24VAC at motor connector, wire #19 (input to

 

blower motor

centrifugal switch) to neutral. If no voltage is present,

 

 

trace wiring back to burner transformer. If voltage is

 

 

present, check for 24VAC at wire #20 (output of

 

 

centrifugal switch) to neutral. If no voltage is present at

 

 

wire #20 and motor is running, replace burner blower

 

 

motor.

 

Ignition control

Check for 24VAC supply to the ignition control. If no

 

 

voltage is present, trace wiring back to centrifugal

 

 

switch of burner blower motor. If voltage is present,

 

 

check for 24VAC at pin #3 and ground (pilot valve).

 

 

NOTE: The Honeywell ignition control has a 30 second

 

 

pre-purge (time delay) built in. If voltage is not present,

 

 

replace ignition control. If the pilot valve is energized,

 

 

check to see that the high voltage igniter circuit is also

 

 

energized. To check, disconnect the igniter lead from

 

 

the ignition control.

 

No pilot flame

If the ignition control is supplied with 24Vac and the

 

 

pilot valve (internal to valve assembly) and igniter

 

 

circuits are energized, visually check for pilot flame.

 

 

This may be done by opening the small inspection door

 

 

on the end of the burner, or by opening the main oven

 

 

door and looking under the lower finger housings on

 

 

the right side of the oven. If no pilot flame is visible,

 

 

check the pilot shut-off valve.

 

Pilot shut-off valve

Check to see that the pilot shut-off valve is open (shut-

 

 

off valve is located between valve assembly and

 

 

burner).

 

Pilot tube

Check for gas pressure at the pilot tube. Disconnect

 

 

pilot tube at burner and connect a manometer to pilot

 

 

tube. If no gas pressure is present during ignition,

 

 

check for blockage in pilot tube or pilot shut-off valve. If

 

 

these are clear, and there is gas supplied to the oven,

 

 

replace the gas valve.

 

Pilot orifice

If there is gas pressure at the pilot tube, check the pilot

 

 

orifice for obstructions. Replace as needed.

 

Burner igniter

Check the burner igniter head for any obstructions, also

 

 

check for frayed or broken wire. Check spark gap (gap

 

 

should be .100 to .125 inch). If there is visible damage,

 

 

replace burner igniter.

 

NOTE: Flame should be on

 

 

at this time

 

Pilot flame, but no

Control transformer

Check for 120VAC supply to the primary of the control

main flame

 

transformer. If no voltage is present, trace wiring back

 

 

to the oven power switch. If voltage is present, check

 

 

foe 24VAC at the transformer secondary. If there is

 

 

primary voltage, but no secondary voltage, replace

 

 

control transformer.

 

Oven control

Check for 24VAC supply to oven control. If no voltage

 

 

is present, trace wiring back to control transformer. If

 

 

24VAC is present, check for a read-out on the display.

 

 

If there is 24VAC supplied, but there is no read-out on
